Ahh! Sorry about that, reading too quickly and was confused.
Well if it helps Samoa as a whole has more Pool/Marina rooms than Fiji.
I actually think your plan is the best for the circumstances… you’re in a room type that is guaranteed to not face construction… the same can’t be said for the Standard view category as that could easily put you in Aotearoa or Fiji facing construction (assuming they intend to keep those rooms occupied).
So worst case scenario you’re in Fiji with a room facing the Marina and you see a construction fence when you walk in/out of your building, but that’s it. Not ideal for sure, but not horrible either (subjective comment there, of course).
FYI, you won’t be in Tonga - that building only has suites.
